The Nottingham High junior scored a second-half hat trick, her second this week, rallying the 11th-seeded Northstars to a 3-2 victory over sixth-seeded Notre Dame Friday afternoon at Msgr. Walter Nolan Field in a pulsating encounter in the first round of the Mercer County Tournament.

“It was definitely a big comeback,” said Davies, whose tally in the 58th minute started the climb from a 2-0 halftime deficit. “We haven’t beat Notre Dame in a couple years so coming back and winning really brings the best out of you. It feels good.”

Davies’ first two goals — separated by three minutes — came on identical plays, with the outstanding Kaitlyn Diamond providing the delivery from a corner kick. On the first goal, Davies beat Irish goalkeeper Victoria Binz to the ball, and that seemed to give the ’Stars new life.

Three minutes later, she struck again, this time redirecting Diamond’s cross past a helpless Binz, who was rooted to her line.

The winner came with 5:11 remaining.

Karli Garzillo played in a perfect cross to an unmarked Davies on the back post.

“At this point, I just want this to go in,” said Davies when asked what was going through her head at that moment.

Just like she did earlier in the week against WW-P North, Davies finished the job. She took a touch, picked her head up and slotted a left-footed shot past a sprawling Binz.

“I’m just speechless,” Davies said. “I didn’t come out thinking I would get another hat trick.”

Her teammates know what she’s capable of.

“She’s incredible,” Diamond said. “She’s the one who had our three in our huge win at (WW-P) North. She’s a great, phenomenal player, and we have great chemistry together on the field.”

Things didn’t start out well for Nottingham (6-7-2) when Kelley Wiese gave Notre Dame (10-5) the lead 10 minutes in. The Northstars failed to clear a corner kick and the senior defender pounced, lofting a shot over goalkeeper Chelsea Toscano.

The game was physical as well. Two Northstar players left with injuries — neither returned — and the Irish’s Jordan Tuttle was cautioned for a late challenge.

It went from bad to worse after Peira Wood handled the ball in the box and Julia Panko stepped up to convert the kick, giving the Irish a 2-0 lead 30 seconds before the halftime whistle.

Notre Dame looked well on its way to the quarterfinals.

But Nottingham had something to say.

“It was absolutely amazing,” said Northstars coach Elyse Diamond. “We’ve been down before in the past. We talked about it at halftime and we were right in the game. Other than those two opportunities, it was a game that was back and forth.”

The Irish poured numbers forward in the final four minutes in search of the equalizer, but a couple of saves by Toscano and some heroic defending helped the ’Stars hang on for the upset.

“We’re a really strong team,” said Kaitlyn Diamond. “We just wanted it more. When we’re down, we just push through it. We have a lot of heart and we’re a really close group of girls. If we get our touches down, we know we can get it done, no matter who we are playing.”

Nottingham will face either third-seeded Pennington or 14th-seeded Robbinsville, who met Friday in a night game.
